GENERAL DESCRIPTION
The AD8661/AD8662/AD86641 are rail-to-rail output, single- converters (DACs). Audio applications and medical monitoring supply amplifiers that use the Analog Devices, Inc., patented equipment can take advantage of the high input impedance, low DigiTrim® trimming technique to achieve low offset voltage. voltage, low current noise, and wide bandwidth. The AD8661/AD8662/AD8664 series features extended The single AD8661 is available in a narrow 8-lead SOIC package operating ranges, with supply voltages up to 16 V. It also and a very thin, dual lead, 8-lead LFCSP. The AD8661 SOIC features low input bias current, wide signal bandwidth, package is specified over the extended industrial temperature and low input voltage and current noise. range of −40°C to +125°C. The AD8661 LFCSP is specified over The combination of low offset, very low input bias current, the industrial temperature range of −40°C to +85°C. The AD8662 and a wide supply range makes these amplifiers useful in a wide is available in a narrow 8-lead SOIC package and an 8-lead MSOP, variety of applications usually associated with higher priced JFET both specified over the extended industrial temperature range of amplifiers. Systems using high impedance sensors, such as −40°C to +125°C. The AD8664 is available in a narrow 14-lead photodiodes, benefit from the combination of low input bias SOIC package and a 14-lead TSSOP, both with an extended current, low noise, low offset, and wide bandwidth. The wide industrial temperature range of −40°C to +125°C. operating voltage range meets the demands of high performance analog-to-digital converters (ADCs) and digital-to-analog 1 Protected by U.S. Patents 6,194,962 and 6,696,894.
